When English researchers from the University of Southampton’s Centre for Maritime Archaeology were mapping ancient underwater landscapes in the Black Sea, they found something incredible.

The Black Sea Maritime Archaeology Project was created to perform geophysical surveys on the sea bed to shed light on why water levels rose so fast after the Ice Age, as this information may help us deal with similar situations caused by climate change.

However, their Remotely Operated Vehicles (ROVs) accidentally came across an eerie graveyard of ghost ships in a Black Sea “dead zone.”

The ROVs had been scanning a dead zone 1,800 meters below the surface when their cameras picked up 40 ghost ships. They are believed to be from the Byzantine and Ottoman Empires, which were founded in 330 C.E. and 1299 C.E., respectively.

“They are astonishingly preserved due to the anoxic conditions (absence of oxygen) of the Black Sea below 150 metres,” said project investigator Jon Adams.

Adams hopes their 3-D recording technique will lead to more maritime archeology practices that aim to leave ancient shipwrecks intact instead of moving them to the surface and ruining them. He also plans to study the area more thoroughly in the near future.

Uber and Disney are giving Star Wars fans a bit more incentive to hail a ride to the premiere of Rogue One: A Star Wars Story with a new promotion that begins rolling out Sunday and should be available in the Uber app in hundreds of cities by Monday. The in-app features, which are available on an opt-in basis (so die-hard Trekkers dont have to endure the pain) will replace the little car images on the Uber map with various Star Wars starships, including the iconic X-Wing.

It doesnt stop at fun graphics, either theres also previously unreleased video content from Rogue One built-in to the app which can be accessed once the features are activated by a user. No hint on what these might be, but Id imagine small featurettes or one-off clips from the film are likely possibilities.

For Disney, this is a smart way to get some last-minute promotion for the film in front of the huge audience of Uber riders out there. Its running December 12 through the 18th, officially, so that will cover the launch window of Rogue One, which debuts in theaters on Friday, December 16.

Its also a clever activation by Uber, since its opt-in by default to avoid confusing or frustrating existing users who arent expecting Star Wars ships all over the place. And tie-ups with major films are a staple of Ubers business model in recent years, including promotions run with Batman v Superman, X-Men Apocalypse and Kingsman, among others.

Now, if only theyd figured out how to make an ACTUAL X-Wing show up at my door for the pick-up. Oh right, theyre working on it.
